Fractionated radiotherapy for spinal tumors: A literature review regarding spinal glioma, ependymoma, and meningioma.

Radiation therapy plays a vital role in the management of primary spinal tumors in adults. However, due to the rarity of these tumor types, the literature on optimal treatment indications and radiation doses is limited. Many treatment recommendations are extrapolated from their cranial counterparts, where more data are available.

Spinal ependymal tumors.

Spinal ependymomas are strictly to be subdivided into intramedullary lesions and extramedullary lesions as they are histologically and genetically distinct. Whereas the intramedullary lesions (SPE) are assigned to the WHO grade 2 and very rarely grade 3, the extramedullary lesions or myxopapilary tumors (MPE) are only as recently also assigned to WHO grade 2. The major difference is that in general, an intramedullary lesion of grade 2 remains confined to the local site of origin, even when rarely recurring after complete resection.

Glial transformation of a DNET: About a case.

Dysembryoplastic neuroepithelial tumors (DNETs) are benign cortical tumors frequently associated with medically incurable focal epilepsy. These tumors occur most commonly in children. Given the fact that they rarely become malignant, the long-term prognosis in terms of mortality is excellent, however its similar appearance with other tumors of the central nervous system increases the potential for misdiagnosis and the risk of a pejorative clinical evolution.

Extensive metastatic ependymoma with long-term progression-free survival with capecitabine plus temozolomide combination chemotherapy: A case report.

We wanted to present a rare case of metastatic grade 2 spinal ependymoma with an atypical course at the time of diagnosis. Temozolomide plus capecitabine chemotherapy was started in May 2018 on a 30-year-old female patient with sacral ependymoma who had extensive lung metastases at the time of diagnosis. The patient remained in remission for approximately 29 months, and the current chemotherapy was continued until it progressed in November 2020.

From Diagnosis to Resolution: A Case Study of Myxopapillary Ependymoma Survival.

Myxopapillary ependymoma (MPE) is a rare, slow-growing tumor that commonly arises in the lumbosacral region of the spinal cord, within the filum terminale and cauda equina. The frequent presentation of MPE is back, sacral, or leg pain. The tumor's size, site, and extension usually influence these symptoms.

Clinical, Histologic, and Therapeutic Pattern of Posterior Fossa Tumors in Children in Cameroon: A Cross-sectional Study.

Introduction: Posterior fossa tumors are significant in pediatric neurooncological populations due to their frequency and morbimortality. We convey a 10-year experience managing pediatric posterior fossa tumors at two reference centers in Cameroon.

Materials And Methods: We conducted a cross-sectional study with data collected retrospectively in the Neurosurgery Department of the Central and General Hospitals of Yaounde from January 2010 to December 2019.

From Spinal Ependymoma to Superficial Siderosis: A Bottom to Top Cause of Progressive Neurological Deterioration.

Superficial siderosis (SS) is an infrequent condition characterized by hemosiderin deposition in the central nervous system, resulting from chronic subarachnoid hemorrhage, often linked to dural mater diseases. Through a case report of a 50-year-old male with severe sensorineural hearing loss and newly diagnosed epilepsy, we explore SS triggered by a spinal ependymoma, diagnosed via resonance magnetic imaging (MRI). This case highlights the necessity of comprehensive neuroaxis imaging to identify treatable etiologies.

Conditional survival estimates for ependymomas reveal the dynamic nature of prognostication.

Background: Traditional survival analysis is frequently used to assess the prognosis of ependymomas (EPNs); however, it may not provide additional survival insights for patients who have survived for several years. Thus, the conditional survival (CS) pattern of this disease is yet to be further investigated. This study aimed to evaluate the improvement of survival over time using CS analysis and develop a CS-based nomogram model for real-time dynamic survival estimation for EPN patients.

Case report on an extremely rare type of ependymoma arising from the thigh.

Introduction: Ependymomas are neuroepithelial neoplasms of the central nervous system that arise from the precursor cells lining the ventricular system and the central canal of the spinal cord. Herein, we report a case of an extremely rare type of ependymoma arising from the thigh. Then, a literature review was performed.

Consensus guidelines for the management of primary supra-tentorial intraventricular tumour for low- and middle-income countries.

Almost any primary or metastatic brain tumour can manifest in intraventricular (IV) locations. These tumours may either originate within the ventricular system or extend into the IV space through growth. Such neoplasms represent a broad spectrum, with supratentorial IV tumours forming a heterogeneous group.
